WHO estimates that there are currently 55 million people living with dementia worldwide, with 10 million new cases being reported annually.
Dementia is incurable. However, physical activity, not overusing alcohol, not smoking, nutritious diet, etc., an reduce cognitive decline.
A multivitamin may help prevent cognitive decline, according to research published in Alzheimer's & Dementia.
A total of 2262 healthy adults (average age 73) without a history of cardiovascular disease, stroke, cancer, or any other serious illness took part in the study.
Participants also reported that they either never took multivitamins before or that they intended to stop during the study.
Cognitive abilities were assessed annually through a battery of tests that included verbal fluency, word recall, and story recall.
Multivitamin supplementation improved global cognition, episodic memory, and executive function in older adults, according to the findings.
A higher rate of improvement was observed in people with preexisting cardiovascular disease, according to the study authors.
Taking a multivitamin for three years also appeared to reduce the effects of aging by 1.8 years, or 60%.
